Reconstruction temperature field by spectrum sectioning tomography

Rest ruction 3-D flame temperature field using one stationary camera system with high speed is put forward in the paper .The basic of this technique is that a 3-D object can be regarded as a series of 2-D parallel sections to combine, Focusing some section, a overlapped image of itself Gauss and other sections' defocused will be captured. While moving camera along a line to shift focused section, a group of overlapped section images then will be attained. By reconstruction algorithm to rebuild each section and primary colors to measure temperature, temperature then could be three-dimensionally reconstructed. Experimental results reveal that this technique is reasonable.
